Hmm...I can understand your pointing out and situation.
But as you know, channel 4 also can be used for boot media when eMMC booting
and SMDKV310 can support it by jumper setting.
I mean it can be modified according to each board's situation for mass
production and we don't need this for SMDK in mainline now.
Thanks.
Best regards,
Kgene.
